    Please review my test results....thanks...

    New owner of a 7 year old, 12,000 gallon, fiberglass pool.


    Just took the sample and tested a few minutes ago:

    Ph - 7.2

    FC - 2

    CC - .5

    TA - 110

    CH - 180

    CYA - 32




    I should add more bleach tonight to try to get the FC to around 4, correct?

    Likewise, I should adjust the pH up to 7.6????

    You do to say how the water looks, but we will assume clear. pH will likely come back up when you add bleach. Aeration will also raise pH. Adding bleach should do it.

    Yes, pool water is very clear blue.



    So, forget adding soda ash and just raise FC to 4? or should I go for a higher number like 7?

    and what about the TA and CH levels? Those are fine?

    I suggest you raise FC ieach evening to about 6 or 7.
    Keep FC between 3 and 6 and never below 3.

    ph of 7.2 is fine and will come up on its own.

    TA is fine - slightly above recommended, but fine.

    CH should be raised to between 220 and 320.
    This is recommended in FG pools to help prevent cobalt spotting.

    Can we see a pic of your pool?

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Re: Please review my test results....thanks...

    I would dose to 7
    Pool calc should be giving you a range of 3 to 7 for FC
    Should try to dose to highest number to help avoid going below the lower number if you miss dosing for some reason
    You never want to go below 3 thatt 2 you just tested puts you at risk for algea to get started
    Ta is ok
    Ch I don't recall the recommended levels for fiberglass
    Pool calc will give you the correct goals as long as you have updated the surface type

    btw, we use borax to raise pH and baking soda to raise TA. When you want to raise your pH without raising the TA, use borax. Soda ash raises both pH and TA.

    You can go to the PoolCalculator.com and figure what effect adding X-amount of chemicals has on your pool. The "Effects of Adding Chems" is near the bottom of the calculator.

    Should I just use the shock level of FC 13 to try to get my CC down to 0?



    I will post a pic of the pool tomorrow, for sure!

    .5 CC is fine and not a problem. No need to shock.

    Alright, so I added 1 gallon of 6% bleach....

    Is there a certain way I'm supposed to be adding the bleach? I read somewhere on this forum that you should pour it in front of a return, towards the deeper end of the pool....???

    or should I be walking around the perimeter of the pool and adding it?

    So I added 1 gallon of 6% bleach last night, per the pool calculator recommendation.

    Today's results:

    pH - 7.3

    FC - 6

    CC - .5


    I didn't bother doing the TA or CH test, as I assume they won't have changed since yesterday.

    I did the CYA test outside, with the sun behind me, and came back with a CYA of 40.


    As promised, here's a picture of my (now trouble free) pool!

    Well, many of us have added bleach both ways, but Pool School recommends pouring in front of a return.........
    Bleach should be added to the pool by pouring slowly in front of a return jet with the pump running. You should pour slowly enough that pouring an entire jug takes more than one minute, preferably two minutes. Leave the pump running for at least 30 minutes after adding bleach.
    Your pool looks great!

    Keep your chlorine up to match the Chlorine/CYA chart and your pool looks really nice!

    In regards to maintenance, I should do a chlorine test at the end of the day when the pool is done being used? Based on the reading, and and looking at CYA of 40, I should shoot for a FC level of 7 or so, instead of the target of 5 listed on the chart?....

    Yes, that would be good.

    Yes, with a CYA of 40, keep the FC between 3 and 7 and never below 3. So, I suggest you shoot for a FC of 7ish each evening.

    I'm at 50ppm CYA, I add chlorine every evening to get up to 8ppm Just a little high, but with summer here and the kids home you never can be over prepared.

    My FC just tested at 3.5, so per the pool calculator, I added just about three quarts of 6% bleach to reach a FC of 7.

    That's just about half of a 1.5 gallon container.....so...3/4 gallon? Does that sound about right for daily maintenance of a 12,000 gallon pool? How much 6% chlorine should I expect to put in a day?

    I started the day with 6, or when I tested in the afternoon anyway..so it must have been 7 to start, as per what dosed at last night. Normal to lose 3.5 FC in 1 day with light swimmer load?

    How much would you say you add every evening? Half a gallon? A gallon?

    What strength, 6%, 12%?
